description abstract | The counterrotating compressor of Rotor-Rotor-Stator (R/R/S) layout is considered to be a crucial technical path for engine thrust-to-weight improvement because it can achieve a high-pressure rise level with low weight and a short axial length. To guide the selection of key aerodynamic parameters in counterrotating compressor design schemes, a zero-dimensional physics–based model is proposed, which can calculate kinetic energy variation across the compressor rotor passages based on enthalpy rise and velocity triangles. Numerical investigations on two counterrotating compressors with different pressure ratios have been conducted employing the Reynolds-averaged Navier-Stokes (RANS) method to validate and support the physics-based model. It was found that the model prediction results and CFD numerical results of two counterrotating compressors showed a global agreement, with the deviations in relative kinetic energy variation coefficient less than 3%, implying the accuracy of the proposed model. This model can be used for the loop iteration between the one-dimensional (1D) and two-dimensional (2D) preliminary design schemes of a counterrotating compressor. | |
